Researchers devise thermally-activated flexible display

The race to create bigger smaller and better flexible displays now has yet another participant, but Weijia Wen and colleagues at the Hong Kong University of Science and Technology are putting a toasty twist on their iteration. The team has reportedly developed a "flexible, thermally-activated electronic display made from a mixture of metal nanoparticles and plastic," which costs far less than most similar alternatives to create and measures just 150-microns in thickness. Moreover, these units are able to change hues based on the surrounding temperatures, and while only fixed patterns are available for viewing at the moment, the crew hopes to implement an array of "thermal pixels" in the future for more dynamic opportunities. A display that warns you of an overheating machine / battery / toy -- who woulda thunk it?
